Three Things Buyers Usually Check
Independent Laboratories
Reports are issued by CTC (China Building Material Test & Certification Group) and Hebei Zhongji Inspection Technology — both CMA / CNAS accredited testing bodies, not our own QC department.
System-Level Type Testing
The seismic bracing system has been type-tested as a complete assembly to GB/T 37267-2018 — load capacity, fire resistance and corrosion performance in one report, not a single component in isolation.
Traceable Report Numbers
Every report carries an issuing laboratory and a report number you can quote back to that laboratory to verify authenticity. Number, standard and test date are listed for each item below.
A Selection of Our Test Reports
The table below is a partial list — an extract from our test programme, covering coating thickness, mechanical properties and system-level performance. Batch-specific and project-specific reports are also available.
